Dear Mark: Calcium Supplements, Goitrogenic Foods, High-MUFA Seed Oils, and Jogging

Today’s edition of “Dear Mark” covers a variety of topics. We’ve got calcium supplementation – does it make sense and is it safe? Then, I briefly discuss cruciferous vegetables, which are said to have negative effects on thyroid health. Some studies support this, but are they an issue for healthy people? I also look at […]

Dear Mark: CLA Supplements

Today’s question comes from Ola and regards CLA, or conjugated linoleic acid. What is CLA? CLA is the “good” trans-fat that occurs naturally in meat and dairy, especially from grass-fed animals. In the stomach of ruminants like cows, sheep, or goats, millions upon millions of bacteria help the animal digest its food. They also help […]

15 Ways to Fight Stress

Do I need to really even say the holidays are a stressful time of year? Every lifestyle blog, magazine, evening news program, and newspaper will have a stress-related feature right about now. I bet Dr. Oz has a “holiday stress relief” show airing. It’s part of the culture – we expect holiday stress and seem […]

A Primal Primer: Iodine

Yesterday I mentioned that sea vegetables are a great source of iodine. “But what is iodine?” many emailers asked. Well, dear friends, iodine is elemental. Let’s take a trip through the land of iodine to learn what it is, what it does for the human body and whether you should make an effort to get […]

The Primal Essentials Kit Now Available! (with Special Limited-Time Offer)

It is with great pleasure and excitement that I am announcing the official launch of the ultimate Primal Essentials Kit – and with it a very special limited-time offer. But more on the special offer in a moment. (Click here if you can’t wait.) The founding of my company nearly 15 years ago, the launch […]

Primal Advice for Acne Sufferers

Included among last week’s “Ask Me Anything” responses were several requests for a Primal commentary on acne. A lot of people have asked for this kind of post over the years. The fact is, it’s a great question. Acne is a common problem that gives too many people too much grief. Our medical establishment’s prescription […]

Vitamin D: Loose Ends

Okay, I’ll admit it. I may have spoken out of turn a couple week’s ago when I tried to completely cover vitamin D in a mere three posts (Deconstructing Vitamin D, Vitamin D: Sun Exposure, Supplementation and Doses, Vitamin D: Confounding Factors). A bunch of questions popped up in the comment boards – so here’s […]

Ask Me Anything and Primal Blueprint Updates

This blog post is a two-parter. First, a progress update. Last March I announced a number of exciting projects I had in the works. I’ve already checked a few things off the list: PrimalCon, held last April, was an amazing experience, and the response to The Primal Blueprint Cookbook and the Primal Blueprint Poster (released […]

Vitamin D: Confounding Factors

Yesterday I recommended 4000 IU of vitamin D each day as a good starting point for most people. Though, it’s difficult – nay, impossible – to provide a perfect, universal prescription for vitamin D3 intake. People, and their lifestyle behaviors and environmental conditions are just too different. It’s like with diet. Everyone does well with […]

Vitamin D: Sun Exposure, Supplementation and Doses

From the presence of vitamin D receptors in our cells and vitamin D factories in our epidermis, along with the central role vitamin D plays in calcium metabolism, immunity, and gene expression, it’s pretty clear that having adequate vitamin D is an essential component of being a healthy, successful homo sapien. And yet, many health […]

Deconstructing Vitamin D

Before phototropic plants began bending toward sunlight, before jellyfish developed ocelli, the light-sensing organs that allow them to distinguish between up (sunlight) and down, before the bikini-clad beach denizens began tanning en masse, and before the first house cat followed the sliver of sunlight around the room all afternoon, our primitive, microscopic marine forebears were […]

Cooking with Bones

Marrow is great and all, but what about the bones that aren’t blessed enough to bear the sacred gel in easily extractable amounts? We can’t forget about those. Chicken backs, beef knuckles, ham hocks, chicken feet, lamb necks, hooves and any other animal-derived matrices of calcium phosphate and collagen fibers are all worth saving, cooking, […]

A Primal Primer: Whey Protein

We’re long overdue for a good, solid post on whey protein. I include it in my Primal Fuel shake mix, a number of readers asked about it after last week’s dairy post, and it’s one of the more commonly used nutritional supplements around, so it’s a no-brainer of a post. What is Whey? Whey is […]

Contest Results: Q&A with Mark

Congratulations to Ed, Wyatt, Ken, VN, and Dan. You have won copies of The Primal Blueprint. As Aaron mentioned, we received nearly 250 fantastic questions. I could spend the next few months writing blog posts to address these questions exclusively. Needless to say, I’ll be using the comment board as a source of future MDA […]

Dear Mark: What is Creatine?

Over the years, more than a couple readers have asked about creatine and whether or not it has a place in the Primal Blueprint. People may be tempted to lump it in with anabolic steroids or other chemical enhancers, but they would be conferring guilt by association. To clarify, creatine is a naturally occurring substance […]

Rapid Fire Q&A: Fish Oil Guide Follow-Up

You guys had tons of questions following last week’s Definitive Guide to Fish Oils. Since the back and forth discourse is my favorite part of doing the blog, I’ll see if I can get to all of them. Let me know if I miss anything! You recommend storing fish oil in the fridge, but how […]

The Definitive Guide to Fish Oils

I was actually a little surprised that we hadn’t already done a Definitive Guide to fish oil when a Worker Bee suggested it to me. We’ve mentioned it enough, and it’s a hot enough topic that I just assumed we’d done a big comprehensive guide to the stuff. But, as my staff so eagerly likes […]

Dear Mark: Calcium for Women

Dear Mark, I have been following the PB way of life quite closely now for about five months, and I haven’t felt or looked better!  Well, following it closely except for the dairy part. My question here is “How do I get all my calcium following the PB?” Also, as a female do I need […]

Lipoic Acid

Every day we run across research that further bolsters the logic of Primal living. However, once in a while we read something that just feels like a good pat on the back, the kind of news that makes us nod our heads smiling or do a little end zone dance if it’s Friday and we’re […]

Dear Mark: Vitamin K2

Dear Mark, I’ve been hearing a lot about vitamin K2 lately. Should I be taking vitamin K2 supplements or is a Primal diet sufficient? Kate Thank you, Kate, for the question. You find it in politics, fashion, entertainment, art, even cooking: the “it” figure, new notable, celebrity du jour. As odd as it is, the […]
